Retrieve list of reports from a given folder on an enterpise server

I'm using VS2008 and trying to get a list of reports stored in a given folder on our enterprise server and then open it up in a viewer. I have looked at a number of samples that bear no resmblance to API that I am confronted with. I have no crystaldecisions.enterprise namespace. I assume this is because I'm using the .net v2.0 objects. Are there any examples using this API to perform this (I would assume) rather mundane task?
